I believe you need to restart it in order to load new dlls. Follow below link: https://forums.asp.net/t/1362530.aspx?Should+replacing+a+DLL+require+IIS+restart+ Note: When you restart all application hosted will be down. To prevent it you need to restart the app pool which is related the application. Anyway if you restart either IIS or AppPool application will loose the session contents. https://stackoverflow.com/questions/744990/best-way-to-reload-web-assemblies-without-iisreset FYI: When you change/update DLLs/drop new DLLs in the bin directory of your web application will that reset IIS?? Answer: NO. It doesn't reset IIS. IIS monitors the /bin directory of your application. Whenever a change is detected in DLLs it will recycle the app domain and re-load the new DLLs.
